Question

Fe(so4)3-fe(oh)3-fe2o3 fe2 o3 fe2 so4 3

Answer 1

1. Fe₂(SO₄)₃ + 6NaOH → 2Fe(OH)₃↓ + 3Na₂SO₄
2. Fe(OH)₃ → Fe₂O₃ + 3H₂O
3. Fe₂O₃ + 3H₂SO₄(разб.) → Fe₂(SO₄)₃ + 3H₂O

Answer 2

It seems like you've provided a list of chemical compounds and formulas related to iron (Fe) and its compounds. Let me break down each of them for you:

1. Fe(SO4)3: This is iron(III) sulfate, a chemical compound containing iron in its +3 oxidation state and sulfate ions (SO4^2-) as anions. The compound is also known as ferric sulfate.

2. Fe(OH)3: This is iron(III) hydroxide, which consists of iron in its +3 oxidation state and hydroxide ions (OH^-) as anions. It's commonly referred to as ferric hydroxide.

3. Fe2O3: This is iron(III) oxide, also known as ferric oxide or hematite. It is a compound containing two iron ions in their +3 oxidation state bonded with three oxygen ions (O^2-) each.

4. Fe2(SO4)3: This is another representation of iron(III) sulfate, similar to the first compound mentioned. It indicates that there are two iron ions present in the compound.

5. Fe2(SO4)3·9H2O: This is iron(III) sulfate nonahydrate, a hydrated form of iron(III) sulfate containing nine water molecules (H2O) per formula unit.

6. Fe2O3: This is a duplicate mention of iron(III) oxide, which is a common compound in iron ores and gives the red color to many rocks and soils.

7. Fe2(SO4)3: Another representation of iron(III) sulfate, indicating that two iron ions are combined with three sulfate ions.

It seems like you've listed different representations of iron compounds, including iron(III) sulfate, iron(III) hydroxide, and iron(III) oxide, along with their chemical formulas. If you have specific questions or if there's something you would like to know more about these compounds, please feel free to ask!
